Other Organisations and bodies who wish to stop us flying the CAA’s take on that :—
“The CAA cannot provide advice on what is, or is not, a legitimate interest or whether restrictions or fees are being lawfully imposed by other authorities. However, any authority or regulatory body should be able to identify the specific laws, regulations or bye-laws that empower it to regulate the use of UAS, or more usually, the land from which they are operated, much as the CAA has set out the regulations that it applies, above. We therefore recommend that if you are unsure of whether a restriction imposed by a body legitimately applies to your flight, you request that information from the relevant authority or regulatory body.
UAS operators and remote pilots are also reminded that ANO Article 241 provides that a person must not recklessly or negligently cause or permit an aircraft to endanger any person or property.”
